  Welcome to Morning Medical with Doctor Chow.
• 0:02
  I'm Doctor Chi-Ming Chow, your host for today's episode where we delve into the latest medical
• 0:07
  and health news from around the globe.
• 0:09
  Today, we're going to explore a fascinating topic that many of us can relate to: how our
• 0:15
  eating habits can affect our sleep.
• 0:17
  We'll be discussing insights from a dietitian who has shared some simple yet effective
• 0:22
  strategies for improving sleep quality through diet, and one common habit that might be
• 0:26
  interfering with your rest.
• 0:31
  Erin Palinski-Wade, a New Jersey-based registered dietitian and certified diabetes
• 0:36
  care specialist, has revealed that what we eat can significantly influence how well we sleep.
• 0:42
  According to her, certain foods can either support a good night's sleep or disrupt it.
• 0:48
  The key, she says, lies in maintaining steady blood sugar levels throughout the day.
• 0:53
  This can help prevent those dreaded afternoon energy crashes and promote more restorative
• 0:58
  sleep at night.
• 0:59
  Palinski-Wade suggests that combining lean proteins, slow-digesting carbohydrates, and
• 1:06
  healthy fats in your meals and snacks is the number one way to stabilize blood sugar levels
• 1:11
  and improve overall sleep quality.
• 1:14
  Interestingly, she highlights tart cherries or 100% tart cherry juice as her top choice for
• 1:19
  sleep support.
• 1:21
  Tart cherries are one of the foods with the highest natural melatonin content, and they
• 1:26
  also contain compounds that aid the body's ability to use melatonin effectively.
• 1:31
  For those struggling with insomnia, she recommends consuming 4 to 6 ounces of 100% tart
• 1:38
  cherry juice or about a quarter cup of dried tart cherries.
• 1:42
  Although research on the effects of tart cherry consumption on sleep quality and duration is
• 1:47
  still limited and mixed, some small studies suggest it can lead to modest improvements.
• 1:53
  In addition to tart cherries, foods and drinks that help reduce inflammation can also support
• 1:58
  better sleep.
• 2:00
  Foods rich in antioxidants and anti-inflammatory compounds, such as nuts,
• 2:05
  seeds, olive oil, and avocados, provide healthy fats and nutrients that may contribute to
• 2:11
  improved sleep quality.
• 2:13
  On the flip side, Palinski-Wade warns about the potential negative impact of caffeine on sleep.
• 2:20
  While a little caffeine can provide a needed energy boost, excessive intake, especially
• 2:25
  close to bedtime, can disrupt sleep.
• 2:29
  She advises limiting caffeine consumption to 300 milligrams or less per day and stopping
• 2:35
  about 10 hours before bedtime to avoid sleep disruption.
• 2:39
  Caffeine acts as a stimulant, and consuming it too late in the day can make it difficult to
• 2:44
  fall asleep and stay asleep.
• 2:46
  It's important to be mindful of how much caffeine you're having and when you're having
• 2:50
  it.
• 2:51
  The goal is to avoid stimulation and inflammation that can result from excessive
• 2:56
  caffeine intake, which can counteract efforts to achieve a restful night's sleep.
• 3:02
  Today's next topic is an intriguing study that addresses the use of computed tomography, or
• 3:08
  CT, coronary angiography in patients who've been suspected of having an acute coronary
• 3:14
  syndrome but have had a heart attack ruled out.
• 3:19
  This study, known as the TARGET-CTCA study, provides some insightful findings that could
• 3:24
  have significant implications for medical practice.
• 3:28
  The research was presented by Doctor Nicholas Mills at the European Society of Cardiology
• 3:33
  Congress in Munich.
• 3:35
  The study aimed to determine whether routine use of CT coronary angiography could help
• 3:41
  reduce subsequent cardiac events in these patients compared to standard care.
• 3:47
  Over a median follow-up period of three years, the study found no significant difference in
• 3:51
  outcomes.
• 3:53
  Specifically, the composite outcome of heart attack or death from a cardiac cause occurred
• 3:58
  in 7.1% of patients who received CT coronary angiography, compared to 7.3% in those who
• 4:07
  received standard care.
• 4:09
  This suggests that routine CT angiography may not be necessary once a heart attack has been
• 4:15
  ruled out.
• 4:17
  Doctor Mills emphasized that implementing these findings could lead to a reduction in
• 4:22
  healthcare costs and simplify patient care without compromising future outcomes.
• 4:28
  The results were simultaneously published in the New England Journal of Medicine, adding
• 4:33
  weight to their significance.
• 4:36
  Doctor Christoph Grani from Bern University Hospital, who discussed the findings, pointed
• 4:40
  out that CT is a diagnostic tool rather than a treatment.
• 4:44
  He noted that while CT can still be used, its routine use in this particular clinical
• 4:49
  scenario may not be justified.
• 4:51
  He suggested that future research should consider contemporary coronary CT phenotyping
• 4:57
  and assess the cost-effectiveness of such diagnostic approaches.
• 5:02
  It's important to note that across Europe, around 30 million people present with acute
• 5:07
  chest pain to emergency departments each year, but only about one in ten of these cases result
• 5:15
  in an acute myocardial infarction.
• 5:18
  This highlights the importance of efficient diagnostic pathways to avoid unnecessary
• 5:24
  procedures and to manage healthcare resources effectively.
• 5:29
  The TARGET-CTCA study included patients from 14 hospitals in the United Kingdom who presented
• 5:35
  with acute chest pain and had a heart attack ruled out but had elevated high-sensitivity
• 5:41
  cardiac troponin levels, indicating an intermediate risk of future cardiovascular
• 5:46
  events.
• 5:48
  Participants were randomized to receive either CT coronary angiography-guided care or standard
• 5:54
  care.
• 5:55
  The results demonstrated that routine CT coronary angiography did not significantly
• 6:01
  alter the risk of future cardiac events compared to standard care.
• 6:06
  In summary, this study suggests that routine CT coronary angiography may not be necessary for
• 6:12
  patients who've had a heart attack ruled out, potentially paving the way for more streamlined
• 6:16
  and cost-effective patient management strategies.
• 6:20
  However, as always, each patient's clinical scenario should guide the decision-making
• 6:25
  process, with CT angiography remaining a valuable tool in certain contexts.
• 6:32
  Let's dive into a study that has caught the attention of many in the health community.
• 6:37
  A new study presented at the European Society of Cardiology Congress in Germany has linked a
• 6:43
  popular artificial sweetener, xylitol, with a potentially increased risk of heart attack and
• 6:49
  stroke.
• 6:50
  Xylitol is commonly used as a low-calorie sweetener and sugar substitute in various
• 6:56
  products, including foods, drinks, chewing gum, and dental care items.
• 7:02
  It's often chosen by those looking to reduce their sugar intake, but this new research
• 7:07
  suggests we might need to reconsider its safety.
• 7:11
  The researchers analyzed data from two large study cohorts, encompassing more than seventeen
• 7:16
  thousand seven hundred participants from Canada and the United Kingdom.
• 7:21
  Over a six-year follow-up period, it was observed that those in the Canadian
• 7:25
  Longitudinal Study on Aging with the highest blood levels of xylitol faced a fifty-seven
• 7:30
  percent higher risk of death, myocardial infarction, or stroke due to cardiovascular
• 7:36
  events compared to those with the lowest levels.
• 7:39
  Similarly, participants from the European Prospective Investigation into Cancer, or
• 7:44
  EPIC-Norfolk group, who had the highest levels of xylitol over a thirty-year period, exhibited
• 7:51
  an eighteen percent greater risk of major adverse cardiovascular events.
• 7:56
  The study revealed a dose-dependent relationship, meaning the higher the xylitol
• 8:00
  concentration in the blood, the higher the risk of cardiovascular complications.
• 8:05
  Interestingly, these heightened risks remained even after adjusting for other factors such as
• 8:11
  age, gender, body mass index, hypertension, diabetes, and lipid levels.
• 8:18
  Doctor Marco Witkowski from Charité University Hospital in Berlin, who presented the study,
• 8:24
  noted that previous research had indicated xylitol's ability to enhance platelet clumping,
• 8:29
  which can lead to clot formation.
• 8:31
  This could be a potential mechanism for the increased cardiovascular risk observed.
• 8:38
  However, it's important to note that this study was observational, which means it does not
• 8:43
  establish a direct causal link between xylitol consumption and cardiovascular events.
• 8:49
  The researchers emphasized the need for further studies to confirm these findings, especially
• 8:54
  as the presence of xylitol in products continues to grow.
• 8:58
  They also pointed out that high blood levels of xylitol do not necessarily indicate dietary
• 9:03
  intake, as xylitol can be naturally produced in the body during glucose metabolism.
• 9:10
  Doctor Aseem Malhotra, a cardiologist and public health advocate based in London, weighed
• 9:16
  in on the findings, stating that the potential mechanism of xylitol increasing cardiovascular
• 9:22
  risk should be taken very seriously.
• 9:25
  He mentioned that in his practice, many patients experience anxiety and palpitations
• 9:31
  that resolve once they stop consuming artificial sweeteners.
• 9:35
  Doctor Malhotra advises his patients to avoid all processed sugars and artificial sweeteners
• 9:40
  for a period of six weeks to break the cycle of addiction.
• 9:45
  Our final topic today touches on an ongoing challenge in the healthcare system: the
• 9:50
  capacity of subspecialists and how we might better utilize these vital resources.
• 9:56
  A recent article by Doctor Fred Pelzman, a contributing writer for MedPage Today, explores
• 10:02
  whether medicine can open up its subspecialist capacity to better serve patients.
• 10:08
  Doctor Pelzman shares an anecdote about a patient who, due to a family history of
• 10:12
  dementia, wanted to see a memory disorder specialist.
• 10:16
  Despite a mild presentation of symptoms, the patient was concerned and sought specialized
• 10:21
  care.
• 10:23
  However, the appointment was scheduled for over a year later, highlighting the significant
• 10:27
  delays and capacity challenges faced by many healthcare systems.
• 10:32
  The article points out that these issues have been exacerbated since the pandemic, with many
• 10:37
  providers feeling burnt out and leaving the profession.
• 10:40
  The demand on the system has led to overbooking, and the ability of patients to
• 10:45
  self-schedule appointments has filled specialists' calendars with cases that perhaps
• 10:49
  do not require such specialized care.
• 10:53
  Doctor Pelzman suggests that chronic disease management is indeed the bread and butter of
• 10:59
  primary care.
• 11:01
  Yet, the current system often sees patients being referred to subspecialists for conditions
• 11:06
  that could be managed within primary care settings, such as stable hypothyroidism,
• 11:11
  well-managed high blood pressure, or mild reflux.
• 11:16
  He advocates for a model where after an initial evaluation by a subspecialist, patients are
• 11:22
  returned to their primary care doctors for ongoing management, with the support of a
• 11:26
  robust team.
• 11:28
  This would include nurses, physician assistants, pharmacists, care coordinators, and
• 11:35
  navigators.
• 11:36
  Such a system could free up subspecialists to focus on more complex cases that truly require
• 11:41
  their expertise.
• 11:44
  Additionally, Doctor Pelzman highlights the potential of artificial intelligence and
• 11:48
  algorithm-driven care to aid in managing these medical conditions, optimizing treatments, and
• 11:53
  adhering to patient preferences.
• 11:55
  This could be a game-changer in how healthcare is delivered, making it more efficient and
• 11:59
  patient-centered.
• 12:01
  The goal is to ensure that when we truly need a subspecialist, they are available promptly.
• 12:07
  It’s a call to rethink how we allocate healthcare resources to improve access and
• 12:12
  outcomes for patients.
• 12:14
  By empowering primary care with the necessary support and resources, we can create a more
• 12:19
  balanced and effective healthcare system.
• 12:22
  And that wraps up today's episode of Morning Medical with Doctor Chow.
